French 47mm ATG was overweight, now by how much? French used a slightly heavier projectile and fired it about 80m/s faster (over 10%). French had more traverse and a larger shield, I don't know the thicknesses of either shield. French gun was not really suitable for "high speed" towing but it...

I am wondering about the soviet flag in the civil war? American flags with only nine stripes? Studying history is hard enough, AI could nearly obliterate it.

A lot depends on the rest of the gun barrel, cradle, carriage, etc. Max elevation and traverse. weight of shield/s. Any towing equipement. What is the towing speed? What is the expected travel distance before breakdown? What is the gun life (number of rounds fired)? What types of...

This is quite true. Some of the technical "solutions" were not really practical at the time. Tungsten carbide worked and worked well, problem was that nobody had very much of it. One book claims that many of the German tanks in Russia had 5 rounds or less in 1941. Which really calls into...

I think some people got caught up in catchy titles in specifications, not just the Germans, that were completely unrealistic. The German mine shells were a very clever innovation in small HE shells, but since they sacrificed sectional density to do it, they had problems with long range, like...

Germans seemed to have a real love of using 3 different guns of different calibers and ballistics (times of flight) on aircraft. Trying to get all three to hit at the same place and time was possible but only at short ranges. Germans shot themselves in the foot with the MG 213. Trying for...

With the AK-47 replacing the Submachinegun the pistol cartridge no longer has to work at 75-150 meters so they can go to the smaller cartridge for the Makarov. It is hard for one cartridge to do both jobs. The French cartridge might have been OK as a pistol round, it was not a good choice for...

Axial plus axial ( or multi stage centrifugal) plus reheat plus a host of other complications. A true triumph of paper complexity overwhelming actual manufacturing capabilities and actual knowledge. https://www.enginehistory.org/GasTurbines/EarlyGT/XJ37/XJ37.shtml It makes the 3 spool engines...

You are close to the Historic US 75mm T45 round tested (issued?) for the M3 gun in the Sherman tank. actual MV of standard M61 round (14.96lbs) 619m/s actual MV of the T45 round (8.4lbs) 867m/s. This was an APCR round so includes the sabot, adjust as you see fit...

You are obsessed with barrel making machinery ;) Sometimes it is important, especially in artillery. Other times a lot less so. A lot depends on the countries involved and the rate of actual production desired. Also the type of steels used in the barrels. A lot of .22LR barrels between the...

Martin had built a number of torpedo bombers in the 1920s and early 30s. But Martin's involvement with carrier aviation faded in the late 30s. They were duking it out with Consolidated for the flying boat market though.

You do have to figure out what you want. Performance at 150 meters (or 200 meter???) Or blow back operation in you hand guns. A 3.5-4.5kg submachine gun can use high powered ammunition in a blow back action. A pistol the size of a Makarov cannot. Makarov operated in the low 20,000psi...

The theory is good (mostly) the execution is the problem. If the APDS does not separate cleanly and consistently accuracy turns to crap. It doesn't matter how good the penetration is if the majority of rounds fired do not hit the target. The next question is deciding on the size of the core...

Germans try the Yak solution for the Meak-1015. But short endurance and needed to glide when the engine flamed out is certainly draw backs.

Sorry, I took the harder to hit as a separate question/problem. The smaller volume for electronics may have been a problem in 1970s through ???? But electronics got a lot smaller over the years for the same capability or they could fit more capability into the same or smaller spaces. The Super...
